3M Cubitron II Resin Bond Grinding Wheel 93BH is a resin bonded wheel featuring a mix of green silicon carbide, monocrystalline aluminum oxide and 3M Precision-Shaped Grains with geometrically defined cutting edges for conventional hot roll grinding operations. These wheels are suitable for high speed steel, cast iron, high and low chrome, as well as continuous pouring cladding (CPC) rolls.Designed for Grinding of Hot Mill Rolls Roll grinding workshops face many challenges, including rising quality standards. 3M Precision Grinding Solutions are designed with these challenges in mind, including 3M Cubitron II Resin Bond Grinding Wheel 93BH. These wheels are powered by a mix of 3M Precision-Shaped Grain, green silicon carbide and monocrystalline aluminum oxide. This grain mix makes 93BH Resin Bond Wheels a great choice for grinding operations of hot mill rolls on high speed steel, cast iron, high and low chrome and CPC. The Science of Oriented Precision-Shaped Grains 3M Cubitron II Resin Bond Grinding Wheel 93BH is powered by a blend of minerals including 3M Precision-Shaped Grain. These ceramic triangular grains are oriented in a specific direction to best optimize the cutting ability of each individual grain. The result is a wheel that lasts longer, cuts faster and runs cooler.
